Hello,  
You seem to be confusing the csh shell variables with GMT parameters. The first part of your script should be setting csh variables but you added “gmt” before the commands. You should only add “gmt” before gmt commands, not the csh commands like “set”.

Dear EJFielding for your quick answer,  
Yes, I removed the gmt from the setting csh variables and I got this error,  
Could you please help me to fix it?  
Best regards

I see no further errors, just warning and information messages. Some are related to your script probably using GMT 4 syntax which results in a warning, and the surface message means you picked a bad combination of -Rw/e/s/n and -I so that the number of nodes in x and y are prime. This means slow convergence since no common factors.
